Herschel 400 Catalogue

The Herschel 400 catalogue is a subset of William Herschel's original Catalogue of Nebulae and Clusters of Stars, selected by Brenda F. Guzman (Branchett), Lydel Guzman, Paul Jones, James Morrison, Peggy Taylor and Sara Saey of the Ancient City Astronomy Club in St. Augustine, Florida, United States c. 1980. They decided to generate the list after reading a letter[1] published in Sky & Telescope by James Mullaney of Pittsburgh, Pennsylvania, USA.[2]

In this letter Mr. Mullaney suggested that William Herschel's original catalogue of 2,500 objects would be an excellent basis for deep sky object selection for amateur astronomers looking for a challenge after completing the Messier Catalogue.

The Herschel 400 is a subset of John Herschel's General Catalogue of Nebulae and Clusters published in 1864 of 5,000 objects, and hence also of the New General Catalogue.

The catalogue forms the basis of the Astronomical League's Herschel 400 club. In 1997, another subset of 400 Herschel objects was selected by the Rose City Astronomers of Portland, Oregon as the Herschel II list, which forms the basis of the Astronomical League's Herschel II Program.

Vital statistics

  • The catalogue contains 400 objects
  • All objects are from the NGC
  • All visible in mid northern latitudes (they were all observed by Herschel from the UK)
  • All visible in 150 mm (6") or larger telescopes

Distribution of Herschel 400 objects

Herschel 400 objects which are also Messier objects

The Herschel 400 contains 17 objects which are part of the Messier catalogue:

Herschel 400 objects which are also Caldwell objects

The Herschel 400 catalogue pre-dates the Caldwell catalogue. The Caldwell catalogue contains 44 objects which are members of the Herschel 400:[3]
